Reverse Osmosis is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by household water pressure pushing the tap water through a semi permeable membrane. The membrane (which is about as thick as cellophane) allows only the water to pass through, not the impurities or contaminates. http://catalogs.indiamart.com/products/reverse-osmosis-systems.html

  • 3. Reverse Osmosis* Reverse osmosis (RO) is a purification technology that uses a semi-permeable membrane. This membrane-technology is not properly afiltration method.* In RO, an applied pressure is used to overcome osmotic pressure, acolligative properties, that is driven by chemical potential, athermodynamic parameter.* RO can remove many types of molecules and ions from solutions andis used in both industrial processes and to produce potable water.* To be "selective," this membrane should not allow large molecules orions through the pores (holes), but should allow smaller components ofthe solution (such as the solvent) to pass freely.* Osmosis is a natural process. When two liquids of differentconcentration are separated by a semipermeable membrane, the fluidhas a tendency to move from low to high solute concentrations forchemical potential equilibrium.
  • 4. Reverse Osmosis Water Purification Systems Work* Reverse Osmosis is a process in which dissolved inorganic solids(such as salts) are removed from a solution (such as water).* This is accomplished by household water pressure pushing thetap water through a semi permeable membrane.* The membrane (which is about as thick as cellophane) allowsonly the water to pass through, not the impurities or contaminates.* These impurities and contaminates are flushed down the drain.* Ultimately, the factors that affect the performance of a ro systemare: * Incoming water pressure * Water Temperature * Type and number of total dissolved solids (TDS) in the tapwater * The quality of the filters and membranes used in the RO System
